What the trial is, and whether it could suit you
Background:
Primary sclerosing cholangitis is a rare chronic liver disease. It affects the bile ducts of the
liver. It can result in bile duct infections, cirrhosis, cancer, and end stage liver disease. Researchers want to learn more about this disease.
Objective:
To understand the biological causes of primary sclerosing cholangitis.
Eligibility:
Adults age 18 and older who have primary sclerosing cholangitis.
Design:
Participants will be screened with a medical history, physical exam, and blood tests.
Participants will give blood, saliva, urine, and stool samples. They will have nasal swabs. They will complete surveys.
Participants will get an intravenous (IV) catheter. A plastic tube is inserted into an arm vein.
Participants will have a colonoscopy. A tube with a video camera at the end is inserted into the rectum.
Participants will have an upper endoscopy. A scope with a
